A RIGOROUS COMPARATIVE RESEARCH INVESTIGATION ON SELECTED AUTHENTICATION METHODS FOR VPN SECURITY

Abstract

In the evolving landscape of digital connectivity, Virtual Private Networks (VPNs) serve as vital conduits for secure and private communication. Authentication methods play a pivotal role in safeguarding the integrity of VPN connections, ensuring that only authorized users gain access to sensitive resources. This research sets forth a comprehensive investigation into the realm of VPN security through a rigorous comparative analysis of various authentication methods. The research aims to address the critical need for a deeper understanding of the strengths and weaknesses of authentication mechanisms used in VPNs. By scrutinizing diverse methods such as username and password, certificate-based authentication, multi-factor authentication, and more, this study seeks to unravel the nuanced implications of each approach in terms of security, usability, and scalability. The research will unfold in two principal phases. The initial phase encompasses an exhaustive review of existing literature, unveiling the historical progression of authentication methods in VPNs, their theoretical underpinnings, and real-world implementations. Building upon this foundation, the study will then delve into an intricate comparative analysis, systematically evaluating each authentication method against predefined security metrics, usability benchmarks, and scalability considerations. The outcomes of this research endeavour are expected to yield insights of paramount significance. By critically assessing authentication methods across multiple dimensions, the study aims to elucidate the contextual suitability of each approach based on diverse use cases and organizational requirements. The anticipated contributions of this research lie not only in its ability to guide VPN administrators, developers, and security professionals in making informed decisions concerning authentication methods but also in contributing to the broader discourse on cybersecurity. The study endeavours to propel advancements in VPN technology, fortifying its role in ensuring secure digital communication across various domains.
